#1 Wire Pi Plus
|
||
|
|
|
||
|
|
1 Wire Pi Plus de AB Electronics UK es una placa de comunicación diseñada para Raspberry Pi A+, B+ y 2 modelo B, compatible con el protocolo 1-Wire®. La placa incluye un puerto I2C de 5V regulable.
|
||
|
|
|
||
|
|
El puerto 1-Wire® en 1 Wire Pi Plus está basado en el componente puente de DS2482-100 I2C a 1-Wire®. El DS2482-100 proporciona una protocolo de conversión bidireccional entre el puerto I2C en Raspberry Pi y cualquier dispositvo esclavo conectado a 1-Wire®. Se utiliza un diodo de protección ESD para proteger 1 Wire Pi Plus y Raspberry Pi de descargas electrostáticas en el puerto 1-Wire®. Las conexiones al puerto 1-Wire® se pueden realizar a través del conector RJ-12 o soldando en el PCB.

La librería Quick2wire [https://github.com/quick2wire/quick2wire-python-api](https://github.com/quick2wire/quick2wire-python-api) permite un acceso sencillo al puerto I2C mediante Python.
